ATTACHMENT FOR ROAD-CULVERTS.

Specification of Letters Patent. Patented J an. 3, 191 1.

' Application filed April 5, 1910. Serial No; 553,508.

To all whom it may concern:

Beit known that I, GEORGE S. P. BRANNEN, a citizen of the United States,residing at Danforth, in the county of lVashington and State of Maine,have invented new and useful Improvements in an Attachment forRoad-Culverts, ofwhich the following is a specification.

This invention relates to improvements in attachments for road culvertsand has for its object the provision of an end wall for the culvertcomprising two sections of sheet metal having corrugated .orplain'surfaces as desired, the-said sections being secured together andprovided on their secured ends with alining openings which cooperate topresent an opening for the reception of the culvert end.

A further object is the provision of an end wall comprising a pair ofU-shap'ed extensions having the terminals of their opposite limbsconnected, whereby an oblong space will be formed for the reception of afilling material such as sand, concrete or the like, which whenpositioned within the.

opening will cooperate with the end wall to provide a solid-anchorcapable of resisting any strain which would have the tendency todisplace the culvert, and to further prevent the stream working its wayunder or around the culvert.

With these and other objects in view, which will more fully hereinafterappear, the present invention consists in certain novel details ofconstruction and arrangement of parts, hereinafter fully described,illustrated in the accompanying drawings and more particularly pointedout in the appended claims; it'being understood that various changes inthe form, roportion, size, and minor details of'the evice may be made,within the scope of the appended claims, without departing from thespirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, forming a part of the specification;-+Figure 1 is a front elevation of the device showing its applicationtoone end of a culvert.- Fig. 2

is a vertical cross sectional view taken approximately on th line 22 ofFig. 1. Fig. 3 is a detail PQISIL'JJtlTB of a modified form of end wall.

Similar numerals of reference are employed to designate correspondingparts throughout.

As shown the device comprises two sections designated in general by thenumerals 5 and 6, each being formed of single pieces of corrugated sheetmetal. It must be understood however, that I am not to be limited'to thespecific use of corrugated sheet metal, since it will be understood fromwhat will appear later, how the device may be equally as wellconstructed from sheet metal having plain surfaces. The sections 5 and 6are each formed by bending an oblong piece of sheet metal intosubstantially a U- shape, the opposite limbs of which are designated bythe numerals 7 and 8. It Will of course be understood that thedimensions of the sheets before bending will be suflicient, after thesections have been formed into U- shapes to permit the wall to span therequired distance where the culvert is located and extend upwardlyto thesurface'of the road, or above the latter as may be desired.

The terminalsof the limbs 7' and 8 overlap and are connected together bybolts or rivets 9 and are provided. on their-bearing surfaces withalining semi-circular recesses which cooperate to present an annularopeningfor the reception of the culvert 10.

The culvert 10 may be constructed of sections similar to most forms ofmetallic culverts and will extend through the space between the limbs ofthe sections; it being understood vthat the wall is preferablypositioned after the culvert pipe 10 has been arranged in the creek orthe like. The angles formed by bending the sheets into their U-shapesare braced by suitable rightangular-shaped brackets 11 arranged on theinner surfaces of the sections.

r A coping is designated in general by the numeral 12 and is formed ofasingle piece of sheet metal oblong in contour and some what greater inlength than the combined lengths of the sections and a'trifle greater inwidth than the width of either section.

downwardly, as shown at 13, and'are spaced from the adjacent outersurf-aces of the sec tions. It will be seen by reference to Fig. 2

that the upper endsof the sections are flexed outwardly, as shown at 14,whereby bearing flanges are provided to engage with the lower surface ofthe coping. The flanges l t are somewhat less in width than the spacebetween the flanges 13 of the coping and the adjacent surfaces of thesections,

when the coping is positioned, as shown in Figs. 1 and 2. Extendingthrough alining openings formed in the flange 14: and body of the copingare clamping bolts 15 which serve to secure the coping to the sectionsin the manner shown.

The modified form illustrated in Fig. 3 is intended to be used for smallculverts, and in I the present instance is shownto comprise a pair ofsections 16 and 17, each formed of a single piece of sheet metalcorrugated and having their inner ends overlapping and secured togetherby bolts or rivets 19, said inner ends being provided with aliningsemicircular recesses which cooperate to present an annular opening 18for the culvert end. The upper ends of the sections are provided withacoping preferably formed by bending an oblong piece of sheet metal atits medial portion and in the direction of its length, whereby sides 20and 21 are provided, portions of which bear on the upper ends of thesections 16 and 17 and are secured thereto by bolts or rivets 22. Theportions ot the sides 20 and 21 extending upwardly and beyond the upperedges of the sections are bulged outwardly, whereby a bead is provided,the said coping operating to strengthen the sections and at the sametime present a neat appearance and conceal the sharpened edges or thesections.

From the foregoing, it is evident that I have provided a device which iscomparall \cly simple in structure and inexpensive in manufacture,embodying few parts and these so arranged that the danger of derangementr:

will be reduced to a minimum.

I claim z I i 1. An end wall for culverts comprising a pair of U-shapcdsections having the terminals of their opposite linibs connectedtogether and provided with alining recesses which cooperate to presentan openlng for the reception of a culvert end a space flanked bv theinner surfaces of the said sect ons pre' senting an opening for thereception ot a filling material, for the purposes described.

2. An end wall for culverts comprising a pair of U-shaped sectionshaving the ternilnals of their opposite linibs connected together andprovided with alining recesses which cotiperate to present an openinglei the reception of a culvert end, the upper end portions of saidsections being provided with lateral flanges and the space between saidsections presenting an opening for the reception of a filling material,and a coping arranged on the upper ends of the sections and sectired tothe said flanges.

In testimony whereof I aliix my signature of two witnesses. T GEORGE S.P. BRANNElN. lVit-nesses 'l. C. C. LrrTLErmLn, -E. W. BU'rrnnrInLn.
